About Michael Sharp and Zaida Catalan (Swedish) working for the UN:
The Congo goverment has a video showing them killed by being shot. In Sweden there speculations that it was not the milisia killing them but instead the goverment.
Below part/quoute what Swedish media (who them selfs probably quoted RFI Radio France Internationale) says about the video.
"Those shooting - who consistently stay outside the camera - are constantly switching languages.
The men, according to the government, belong to the Kamwina Nsapu guerrillas, speak in Lingala and French, the languages used by the government army. And when they switch to tshiluba, the guerrilla language, according to RFI, they commit several language errors. Even the fact that the area, where the UN experts were killed, were controlled by the Congolese army puzzling."
